Explore the story in 3 minutesThe week witnessed significant upheaval in global trade due to President Trump's abrupt tariff actions, which threatened established trade rules and created economic turmoil [para. 1]. Initially, the U.S. implemented "reciprocal tariffs" on April 9 with a 10% baseline rate and higher rates on 64 countries, including a 104% levy on China [para. 2].

A tumultuous week for global trade saw established rules pushed to the brink by President Trump’s tariff actions and abrupt policy reversals, shaking markets and alarming America’s trading partners.
After announcing sweeping tariffs on April 2, the Trump administration implemented its “reciprocal tariff” system on April 9. The policy applied a 10% global baseline, but imposed higher rates — up to 46% — on 64 countries, with China facing a 104% levy.

In April 2023, China and France decided to build a “from French farms to Chinese tables” supply chain mechanism — it turned out to be a banner project for Sino-French cooperation, with France now China’s largest agricultural product import market and second-largest agricultural product trading partner in the EU.

AbstractQuantum communication realizes information-theoretic security using photonic quantum states, for example, quantum secure direct communication (QSDC), which can achieve secure and reliable communication in a channel with both noise and eavesdroppers. However, QSDC suffers from large losses and short communication distances, thus being impractical for applications. Here, we have proposed a one-way quasi-QSDC protocol with single photons.

AbstractThe ubiquitous occurrence of toroidal vortices, or vortex rings, in fluid dynamics scenarios in nature has garnered notable attention in the scientific community, while their electromagnetic counterparts have only been proposed recently with two distinct manifestations: vector toroidal pulses and scalar phase toroidal vortices.

AbstractGlycosylation chemistry plays a pivotal role in glycoscience. Recent substantial developments have poised the field to address emerging challenges related to sustainability, cost efficiency, and robust applicability in complex substrate settings. The transition from stoichiometric activation to metal-catalyzed methods promises enhanced chemoselectivity and greater precision in controlling glycosidic bond breakage and formation, key to overcoming existing obstacles.

AbstractIn soft matter systems, there is a wealth of topological phenomena, such as singular disclination lines and nonsingular defects of skyrmions and hopfions. In a liquid crystal (LC), the topological nature of disclination lines and colloids induces chiral colloidal entanglements. How the chirality of the entanglements is deterministically created and how the chirality conversion is actuated in the disclinations with Möbius strip topology have never been explored.

AbstractTwo-dimensional (2D) materials are emerging as a promising platform for epitaxial growth, largely free from the constraints of lattice constant and thermal expansion coefficient mismatches. Among them, transition metal dichalcogenides (TMDs), known for their superior electrical properties, are ideal for ultrathin semiconductor applications.
